I think I'll just leave it alone since the truck stops fine and I have so many other projects to deal with right now.

My wife recently drove the truck, after the repair, because I was working on her regular vehicle. She called me from the road saying the pedal went all the way to the floor and felt soft. She got home and I went for a test drive and was like, what are you talking about? It's always been like that. I did have the brake line going to the back rupture a while ago. Maybe 4 years ago. I had someone else repair it as it was winter time and I don't have a garage and my hands can't tolerate the cold. I can not remember if the pedal feel changed at that point.
The only way I was able to get a decent pedal feel was to use the bleeding technique seen above.
You must make up three nipples to the ABS HCU.
You could get them at the junkyard. And then use the 5/16 vinyl tubing from the nipples and submerge into the MC. Then press and hold the brake pedal. Repeat many times. Then run scanner ABS bleed many times. And then repeat process again.

I just picked up a 2005 1500 short bed with a plow.
The Kelsey Hayes Rear Wheel Antilock only has such a better brake pedal feel.

I wish the 2500 had this system!
